. Application filed June Ill, 1883. (No model.)

To all whom it may concern,-

Be it known that I, SAMUEL B. BUSHFIELD, a citizen of the United States,residing at Denver, in the county of Arapahoe and State of Colorado,have invented certain new and useful Improvements in Apparatus forGenerating and Garbureting Hydrogen Gas and I do declare the followingto be a full, clear, and exact description of the invention, such aswill enable others skilled in theart to which it appertains to make anduse the same, reference being had to the accompanying drawing, and

to theletters and figures of reference marked thereon, which forms apartof this specifica.

tion.

This invention relates to certain improvements in apparatus forgenerating and carbureting gas for illuminating purposes; and it hasforits objects to provide for thoroughly carbureting the gas, so as toproduce a steady, uniform, and brilliant light,.and to produce 1 anapparatus which will be simple and inexpensive inconstruction, easy tomanipulate, and perfectly autom atic in operation. These objects Iattain by the means illustrated in the accompanying drawing, in which'is represented a vertical sectional view of my improved apparatus.

In the said drawing, the letter A indicates the carbureting-chanlber,which consists of a closed vessel of metal or other suitable material,preferably of cylindrical shape. Near the bottom of said vessel islocated a horizontal ber, as shown.

packed with some absorbent materialsuch as diaphragm or partition, B, ofmetal or other suitable material, which is provided with one' or moreseries of annularly-arran ged apertures, 0, near its edge, for thepurpose hereinafter explained. Above said diaphragm or partition islocated a metallic dome, D, which sets loosely upon said partition, andwhichis provided with a series of openings, E, as indicated, and abovesaid dome, in the carbureting} chamber, is a diaphragm or partition, F,from which extends upward short pipes G into the upper compartment ofthe carbureting-cham- The .said upperchamber is sponge, excelsior, orthe likef0r the purpose hereinafter explained. The top of the chamber ishermetically fastened to it, and is providedwith a service-pipe, H,leading to one the flow of gas may be regulated.

or more burners, one being illustrated in the present instance, eachburner being provided with a suitable stop-cock, I, by means of whichThe said top is also provided with a filling aperture or pipe being bentdownward at its upper end, as shown, and its extremity passed below saiddiaphragm, as indicated, for the purpose here:-

inafter set forth.

The letter R indicatesra cock for withdraw ing the spentcarbureting-fluid from the lower compartment of the carbureting-chamber,and S a similar cock for drawing off the spent fluid from the uppercompartment. 7

The letter T indicates the generatingchamber, which consists of a vesselof copper, lead,

glass, or other material capable of resisting the action of sulphuricacid. The said vessel is of such size that the carbureting-chamber maybe fitted upon its top, as shown. Within said vessel projects downwardlya bell of non-corrosive material, which is connected to the lower end ofthe tube by a gas-tight joint, the tube communicating freely with itsinterior. From the said tube depends a wire, U, hooked at its lower end,to which may be attached a perforated copper basket, V, provided withperforations W, for the purpose hereinafter set forth.

The operation of my invention is as follows: The gasgenerating chamberis charged with a solution of sulphuric acid in water to abouttwo-thirds of its height, (more or less,) and the basket filled wit-hscrap zinc or iron and secured to the hooked wire. The carburetingchamber is then charged through the'fillingaperture with hydrocarbonfluid of proper specific gravity. The said fluid first collects 'in theupper compartment until it reaches the generating-chamber, the bellextending down into the acid solution in said chamber. Upon opening oneor more burners the pressure in the bell will be relieved, the acidsolution will' enter it and come in contact with the zinc or ironscraps. Hydrogen gas will be thereby generated,,which will first forcethe air up through the carburetor and out of the same, after which thegas will commence to flow through, taking the direction indicated by thearrows. The reaction of the acid upon the zinc will develop a certainamount of heat, which will be carried up by the gas and imparted to theliquid in the lower compartment to assist in its volatilization. Thedome com pels the gas to pass to the center of the lower chamber,preventing the gas from carrying up any acid or watery vapor into theupper chamber, which might injure the packing, and distributing the gasinto the upper part of the lower chamber in such manner that it willpass uniformly to all of the tubes leading to the upper chamber, so asto .distribute it uniformly throughout the packing. The gas in athoroughly and uniformly carbureted condition finally passes through theservice-pipe to the burner or burners, where it is ignited. By wholly orpartially turning off the gas the pressure in the bell is increased to agreater or less extent, exposing more or less zinc to the action of theacid, thus rendering the machine entirely automatic in its action.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, 1s

The combination, in an apparatus for the manufacture ofilluminating-gas, of the carburetor having a perforated diaphragm nearits bottom, a loose perforated dome resting thereon and provided withperforations at its center, an upper diaphragm provided with up righttubes extending into a packing-chamber, with a central bent tubeconnecting with a generator' and leading to the space below thelowerdiaphragm, a gage pipe connecting the upper and lower chambers of thecarburetor, and an eduction-pipe leading to one or more burners,substantially as specified.

In testimony whereof I affix mysignature in presence of two Witnesses.
